PLURAL SELECTION ADAPTER FOR DELAY V MECHANISM 1 Albert H. Reiber, Evanston, Ill., assignor, by mesne assignments, to Teletypesetter Corporation, a corporation of Delaware Application March 4,

22 Claims.

.The present invention relates to linecasting and composing machines and more particularly to control units for mechanically and automaticall operating suchmachines.

In the coordination of various composition operations under the control of perforated tape sensing mechanism capable of high speed operation, certain operations are encountered in linecasting and composing machines which inher- 1 ently are .,slow compared with other operations, such as matrix release, etc. To coordinate the several operations performed at different rates, delay apparatus has been perfected which institutes a time delay to compensate for the aforesaid inherent slowness and to bring more eliectively the various functions under the control of a single record sensing mechanism. Accordingly, an object of the present invention is to provide a selector unit that will respond to several different signal selections for initiating the performance of mechanism for introducing a predetermined delay in the completion of operations under the control of the selectorfunit. 4 I

Another object of the invention is the provision of a control unit for composing machines having its elements in a simple and compact arrangement to effect a variety of selective conditions.

In U. S. Patent No. 2,090,654 to L. M. Walden, there is illustrated a typical time delay apparatus that is made responsive to a pair of signals for the attainment of the rail shift control operations. There, as will be noted, the allotted signals vary from each other by one signal element or characteristic. Where it is desirable 'to enlarge the scope to which the delay mechanism may be made responsive, the mere additional modification of code bar notches which serve a common selectable element may not sufiice, as may be understood by those acquainted with permutation code system apparatus, The modification of a code bar to permit aselectable element to be selected in either of the selective positions of. the-code bar is termed code bar mutilation. 'It is accomplished by providing a selection notch in place of .a blocking lug in certain ones of the selector bars sothat bars treated in this manner have no. control over the selection of the selectable element. tion of a' single code bar relative to a particular selectable element is efiectedby removing one of its blocking lugs and results in the selective response of that element to two signal combinations instead of but. one. The formation of mutilation notches in more than one code bar may ultimately enlargethe selective scope not simply in an arithmeticalprogression, but will, 'as the included code The mutilaw 1935, Serial No. 9,136

notches are imposed compositely over one posi-- tion, enlarge it geometrically; that is, where a code position such as 0, l, 2, 3, and 4 is mutilated to the extent of one code bar (for example) in the No. 3 position, the affected selectable bar would 5 be responsive also to the code signal combination 0, I, 2, and 4. If this code position is thereafter modified by the superimposed or composite mutilation (for example) of the No. l code bar, the result would permit the selection of the particular selectable bar not only responsive to the afore-- mentioned two code signals but also to the additional code signals 0, 2, 3, 4, and 0, 2, 4. It will be observed then that as a result of the mutilation of two code bars instead of merely one, the selectable 15 class is enlarged to embrace four instead of two code signals, omitting thereby the limited condi- J tion of a selectable class responsive to but three signals. a

Further, as a result of the mutilation of three code bars, the selectable class of signalsto which a given bar may be made responsive is equal to eight, etc. As the-number'of mutilated code bars is increased to enlarge the class of signals to which a'given selectable bar may respond, the number Of'ClfiSS selection possibilities increases geometrically andior this reason there cannot be attained, by the composite code bar mutilation method, certain specific selectable class groups which may be regulated in their number to any of the quantities three, five, six, seven, nine, ten, etc but instead only tothe quantities two, four, eight, sixteen, etc. Expressed -mathematically, the number of signals thus affected isequal to two raised to a power indicative of the number of affected code bars. Thus in the final example taken above three code bars were modified, making the resulting change two to the third power, a or eight, Because of the mathematical limits inherent in the system of secondary selection by superimposed code notches by reason of which any specific number'of secondary selections may not be assured, the present, system has been developed so that any definite number of permuta" tion codesignals and any certain signal of a code order may be included in a class to be delegated to a supervisory or'preparatory operation.

According to this system, a plurality of selectable elements may be employed for exercising the same supervisory control, and by various combi-- nations ofmutilated and non-mutilated code bars controlling the selection of said elements, the supervisory function may be activated in response to .any desirednumber of signal combinations, including those numbers intermediate the terms of the geometrical progression. Thus the supervisory function may be made responsive to three signal combinations by providing two selectable elements, each operable upon the same supervisional mechanism, and mutilating one code bar with respect to one only of the selectable elements. Control of the supervisory function by four code combinations (it being noted that four is one of the terms of the geometrical progression) may be accomplished in two ways, one of which is in accordance with the method previously set forth; namely, the mutilation of two code bars with respect to a single selectable element, or it may be accomplished by providing two selectable elements and mutilating one code bar (not necessarily the same bar) with respect to each selectable element.

Control by five combinations maybe effected by' providing two selectable elements, with respect to one of which two code bars are mutilated, and with respect to the other of which no code bar is mutilated, or by providing three selectable elements with respect to two of which one code bar (not necessarily the same code bar) is mutilated, and with respect to the other of which no code bar is mutilated. In this manner the plural selection of a supervisory or other function may be extended to any desired number and may be definitely limited to any desired number intermediate any two terms of the geometrical progression.

By means of the present invention, any preexisting assignment of code signals for the selective operation of certain several functions may be committed to the supervision of a delay mechanism orto any other intervening agency without affecting the remaining codes not intended to be thus included. The principles of the present invention, in addition to the foregoing objects, permit also of a universal adaptation of code signals into a supervisory class so that where in a primary structure the selectable elements might be miscellaneously or sporadically distributed throughout the physical range of a set of selector bars,fthey may, nevertheless, be embraced within a predetermined supervision. This permits of a reassignment of signals toa secondary control or supervision without regard to the existing assignment in the principal grouping or to any arbitrary sequence or arrangement.

For a more comprehensive understanding of the present invention, reference may be had to the accompanying drawing and to the following detailed specification in which similar reference characters designate corresponding parts throughout, and in which, I

Fig. 1 is a diagrammatic view illustrating compositely the various elements of a linecasting machine to be coordinated with a delay mechanism supervision having one form of the present invention embodied therein,

Fig. 2 is a transverse sectional view of a delay mechanism apparatus such as that illustrated in Fig. 1 or as more detailedly described in'U. S. Patent No. 2,090,654, and

Fig. 3 is a detailed perspective view showing the assembled arrangement of the tape feed mechanism and its operating cam.

Referring now more particularly to the accompanying drawing, the reference character II indicates generally a record reader mechanism for sensing the transverse rows of perforations in a control form or tape I2 and for intermittently advancing the control form I2 by means of the sprocket wheel I3 so as to present consecutively .the transverse perforations to a position where ratchet wheel 35.

they may be sensed cyclically by a set of feeler levers I4.

In the particular embodiment, the apparatus has been designed to accommodate a six-unit code system so that accordingly there are contemplated six feeler levers I4. An additional lever I5 generally similar to the levers I4, except that it is not provided with a tape sensing arm but only with the transfer projections I6 and I! (Fig. 2), is supported intermediate the levers I4 upon a pivot shaft 20. The tape feed sprocket I3 is mounted upon a shaft which also carries a ratchet wheel I8 that is rotated one tooth step at a time during the reciprocal movement of a lever I9, which carries the feed pawl 2|. As may be noted from Fig. 3, tape feed arm I9 is preferably made of sheet material channeled to form a cradle, the sides of which straddle the pivoted end of a lever 23 on shaft 26. A follower roller 22 carried by one end of lever 23 is actuated cyclically by a tape feed mechanism operating cam 24 which is secured to a shaft 25 to be hereinafter identified under the general term, record reader operating shaft.

The pivotal center of lever 23 coincides with that of lever I9 at the shaft indicated 26 in Fig. 2, and the movement imparted to lever 23 by the cam 24 is communicated through the adjustment screw 21 to the opposite end of lever I9 which is shaped with a horizontal projecting portion indicated 28. Another lever indicated 29 also pivots about shaft 26 and is secured to and operates integrally with the principal reciprocating lever 23. A spring 3I secured to the lever 29 or to lever 23 (Fig. 3) urges the assembly clockwise into contactual engagement with the cam 24 while lever I9 is provided with an individual spring 32 for urging its return movement in the same direction independently of the integral assembly comprising levers 23 and 29. Thus it will be seen that while levers 23 and 29 may be continuously reciprocated by the action of cam 24, lever I9, by being withheld in theposition illustrated in Fig. 2, when its projecting arm II 9 is blocked by an arm 31 (to be described later),

may remain dormant so as not toactuate the tape feed ratchet wheel I8.

A feed pawl 33 is pivoted at 34 to the lever 29 and is designed to engage the teeth of a ratchet wheel 35 when permitted to do so. Under ordinary conditions of operation, the tooth of pawl 33 is withheld from engagement with ratchet wheel 35 by a laterally extending pin '36 secured to one arm 31 of a cradle assembly 40 which alsoincludes the transverse connecting member 38 and which is pivoted through opposite ears 39 upon suitable trunnions 4I provided in the supporting structure.

The ratchet wheel 35 forms part of an integral assembly that includes also a companion ratchet wheel 42, the common shaft 43 upon which the two are secured, and an adjustable stop arm 44 for regulating the angular rotation of shaft 43 and in this way controlling the time interval of the delay. A coil spring 45 concentric with the shaft 43 urges it clockwise, as viewed in Fig. 2, to a position determined by the stop arm 44 which comes into engagement with a fixed stop pin 46, Fig. 2. Upon the reception of certain selecting signals, the cradle assembly 40 is rocked counterclockwise about the trunnions 4I, moving the lever arm 3! inwardly and withdrawing pin 36 so as to permit thepawl 33 under the influence of its spring 30 to engage the teeth of the principal Thereafter the reciprocal ofthe associated transfer lever 52.

movement of lever 29, which it receives through lever 23 from cam 24, continues through pawl 33, rotating ratchet wheel 35 and shaft 43 in a stepby-step manner. A latching pawl 50, cooperating with the companion ratchet wheel 42, prevents the return of shaft 43 during each single step operation.

When the shaft 43 ultimately reaches a point as indicated in Fig. 2, a horizontally extending pin 41 carried by the ratchet wheel 35 comes into engagement with the projection 48 of a kick-01f lever 49 loosely carried upon'shaft 43. As a result, an adjustable screw 5! carried by lever 49 comes into engagement with and thereafter moves the intermediate lever l5 from its normal or counterclockwise position to its opposite or clockwise position featured in Fig. 2. In so doing, the transfer projections l5 and II of lever l5 are thereby altered'in position with respect to the projections It is to be noted that shaft 25' continues in operation, providing the power for rotating the escapement shaft 43 and also for reciprocating the several transfer levers 52 which receive the setting from the transfer projections I6 and I1 and instantly impart them toa corresponding set of connecting links 53, the opposite ends of which are interlocked with the six standard or primary code bars 54 as well as with the intermediate blocking bar 55 as described in the aforementioned patent. The bar 55 is connected through one of the links 53 with a transfer lever 52 which receives the setting from the intermediate lever l5 aforedescribed. While the several code bars 54 in accordance with their system of notches are, designed to provide a transverse clearance to one of a plurality of selectable elements or bars 56 upon each setting thereof, the blocking bar 55 differs therefrom by being provided with certain lugs 51 presentable into the path of those selecting ele ments only whose functional response is to be delayed by the mechanism which is described in the instant case including the bars 53 and 59, the latter being illustrated as controlling through the linkage, indicated generally 6|, the movement of the bold-roman shiftable rail 52. When, after the lapse of apredetermined time interval the special lever i5 is rocked out of its normal position by the kick-01f lever 49, the change is communicated to the blocking bar 55, withdrawing the latter from effective position and accordingly permitting the, selection of the particular selectable element (58 or 59) whose code signal is in readiness by presentation of a transverse alignmerit of notches in the standard code bars 54 in its path of selective operation.

It will be understood that upon the reception of azparticular set of code signals to which a delayed function is to be interposed, the alignment of notches presented to its related element 56 may correspond with that which inaugurates the intervention of the delay mechanism, and where the particular codes to be thus served are few in number, for example two, the provision of a duplicate set of notches to accomplish the selective actuation of tape feed blocking arm 3! amounts simply to a duplication of the notches for servingthe delay mechanism selecting element. An example of one such embodiment is that illustrated in the patent referred to above. Where a pair of codes are to be thus served varying in but a single characteristic, one of the code bars may be provided'with a notched area in each of its alternative positions, but where a greater number of codes are to be thus served, the cutting of duplicate notches in other ones of the selector bars 54 or connecting bars 53 which may be referred to as a superimposition of several codes upon each other, may enlarge the selection beyond that intended, as explained above. Accordingly the present invention provides a means for serving any desired number of signals of a code system for inaugurating the delay mechanism operation without enlarging the number of signals which may be afiected beyond that actually required or designated.

In obtaining the above results, the present invention contemplates an extension of code surface area by the provision of auxiliary code sections 63, each of which corresponds to one of the code bars 54 or blocking bar 55 but which is illustrated as being integrally formed with the connecting links 53. The notches (not shown) provided on the extensions 63 may correspond with those provided for the selection of the principal elements 56 in bars 54, or they may, if preferred, provide additional selecting surface for the selection of new code elements which may not be included within the general class 56, thereby obtaining anincrease in the total selective possibilities without having to extend longitudinally the length of the principal selector bars 54. In the case of keyboard mechanism to which the present improvement relates, this structural advantage is important towards the end of maintaining the overall longitudinal dimensions of the control unit or in keeping it at a minimum.

In the featured adaptation, the selectable elements served by the extensions 63 are shaped in the form of nested bails assembled into two groups and indicated 64-439 and H. To obtain the nested relationship of the several bails, each is designed progressively larger than its preceding one of the groups. Bails 64 through 51 are pivotally supported at 13 from projections 12, while bails 68, 69, and H are similarly supported at pivotal centers 14. Each of the balls 64-69 and H is provided with an individual spring which tends to urge it into engagement with the code extensions 63.

In accordance with the particular allotment, the selectable bails 64 through 65 have been assigned to code signals heretofore unemployed or unassigned, which control the three electrical contactors through 17, which in turn control corresponding circuits leading to a storage and distributing mechanism indicated generally 18. The impulses initiated by the closure of these contacts variously control the energization of a set of magnets 19, BI, and 82 that execute the various functions of a quadding and centering apparatus, of which a more comprehensive understanding may be obtained from copending application Serial No. 759,832, filed December 31, 1934.

The succeeding pair of bails 61 and 68 are employed for the completion of circuits leading to a pair of operating magnets 83 and 84. These magnets actuate associated magazine shift or mixer control levers 85 and 86, the actuation of each of which restores the alternative one to its normal position, in this way controlling the so-called mixer apparatus which permits of the selective control of matrix composition from a pair of magazines 8'! and 88. A more comprehensive disclosure of a magazine shift apparatus may be obtained from U. S. Patent No. 1,263,117.

In the illustration of Fig. l, the reference character I ll) designates the key tops which are manually controllable for the operation of release reeds I20, it being understood that means are also provided under the control of the individually selectable bars 56 for automatically actuating the reeds I 20 in a manner such as disclosed in copending application Serial No. 600,606, filed March 23. 1932. I

For convenience in coordinating the selection, the code combinations allotted to the selection of bails 67 and 58 differ from each other by but one code element, having marking signal conditions in positions such as, for example, 9, I, 4, and I], I, 2, l, 5 and spacing signal conditions in the remaining or undesignated positions. In the same way, the two code signals for selecting the elements 58 and 59 differ from each other by but a single code element; such as, 6, I, 2, 4 and 0, I, 2, 3, 4. The particular allotment is a matter of convenience and may be varied in accordance with arbitrary design or any other requirements if so desired.

One of the bails 69 and II is selectable in response to the signals to which the duplex rail selectable bars 58 and 59 are individually responsive and the other is selectable in response to the signals to which the font changing selectable bails 61 and 58 are individually responsive. Thus, with respect to bail 69, it will be understoodthat a selective alignment of notches is permitted during the reception of either signals 0, I, t, 5 or 6, I, 2, 4, 5, thus the code bar extension 63 corresponding to the No. 2 position is notched in both of its alternative positions with respect to bail 69, while in like manner bail II being responsive to codes (I, I, 2, 4 and 0, I, 2, 3, l, the extension 63 relating in this instance to the No. 3 code element impulse, is notched in both of its alternative positions opposite the transverse portion of this bail. For convenience in referring to the bails 59 and II and for distinguishing them from their associated principal selectable elements 58-59 and 67-59 they (bails 59 and 'II) will be referred to hereinafter'as the secondary selectable'elements while their related principal factors may be referred to as the primary or principal selectable elements.

Noting now particularly the peculiarities of blocking bar 55 it will be observed that it is provided with but few projections 57. In the instant adaptation, the projections 5'? are presented so as to block the selection of the primary selectable elements 58 and 59 during the normal disposition of blocking bar 55. In a corresponding manner the intermediate extension 63 associated with blocking bar 55 and particularly with link I08 is provided with a pair of projections (not shown) like the ones indicated 51 on bar 55. These, too, serve to block the selection of the primary selectable elements 6? and 68 during the normal disposition of the blocking bar extension 63.

On the edge of blocking extensor 53 which aligns with the secondary selectable elements, bails 69 and 7!, during the normal position of said extensor notches are provided so that in response to either pairs of code signals ii, I, 4, 5 and ii, I, 2, 4, 5, or 9, I, 2, 4 and ii, I, 2, 3, "i, the bails 69 and II respectively are immediately admitted into selective operation while their associated primary or principal code bars are blocked rom such operation by reason of the aforementioned blocking notches 5?. The selective actuation of bails 69 and 'II is but momentary, however, and upon their restoration by the stripper blade HiI, as will be described, blocking bar extensor 63 may be free to move longitudinally to its non-blocking position (of the primary selectable elements 5859 or 61-68).

A bail 86 which may also be pivotedat III with 64-66 inclusive.

the group 68, 69, and 'II has integrally formed with it an overlying projection 81 which extends beyond the parallel arms 88 and 89 of secondary selectable bails 'II and 69 so that upon the selection of either of the latter bails resulting in the clockwise movement thereof, projection 81 is encountered and receives therefrom a corresponding clockwise rotation about pivot I4. The motion of bail 85 is communicated through an oppositely extending arm 9i and a link 92, which is connected at 93 to the aforedescribed cradle or bail structure 49 pivoted on trunnions II. This movement rocks the cradle 40 in a counterclockwise direction, withdrawing the blocking arm 31 .and its pin 36 from engagement with the escapement pawl 33. In this position the cradle 40 is latched when its transverse tableportion 38 cams down upon the inclined edge I05 of a latch pawl I96, permitting the latter to return under the influence of its spring I61 and thereby preventing the return of the cradle structure 40 when, during a subsequent portion of the operating cycle, the bail selector mechanism is restored. The restoration of the bail structure 40 awaits the release of latch I56, which operation is consummated by the connecting link indicated I08. This link is associated with the blocking bar 55 and the blocking bar extension 63 relating thereto. As indicated at I09, the bar of link I08, differing in this respect from the other links 53, is provided with an inclined cam surface which comes into engagement with and rotates a transversely extending portion III associated with latch I99, rocking the latter in a counterclockwise direction and releasing the cradle 4!]. Following the operation of the delay mechanism, when the blocking bar 55 and its associated connecting link I58 are moved to the right as viewed in Fig. 2, pawl I96 is freed and is then again permitted to respond to the influence of its spring ID'I. In this way the escapement mechanism is initiated not only in response to either of the pair of selecting signals assigned to the boldroman cod-e bars 58 and 59, but also to the selecting signals assigned to the operation of the mixer apparatus selectable by bails 61 and 68. To extend this principle of construction for accommodating additional signal codes, it is but necessary to provide additional secondary selection bails such as those indicated 69 and. 'II and to extend the projection 81 of the common actuator or motion recipient 36 so that the selective actuation of the secondary selection bails is imparted thereto.

Selectable bars 56 and bails 64-66 inclusive are assigned to the control of operations which may be initiated immediately upon the transfer of the related signals and for which no delay or other modification of response need be interposed. Selectable bars 58 and 59 and bails 61 and 58 are assigned tothe control of operations, the initiation of which may need to be delayed. The bars 58 and 59 and the bails 6'! and 68 are not immediately responsive to their respective signals but are normally blocked by the blocking bar 55 or its auxiliary section I68 respectively, a condition which does not obtain with reference to the previously identified bars 56 and bails The selectable bars and bails 56, 58, 59, and 64-68 inclusive comprise the hereinbefore mentioned primary or principal selectable elements.

Bails 69 and II are controlled by the auxiliary code bar sections 63 and are not normally blocked by auxiliary section I08. They are therefore 40 modifications and variations may be made withcapable of responding instantly to their assigned signals. Simultaneously with the response of one of the bails 69 and II to a signal, that one of the selectable bars 58 and 59 or the balls 67 and 58 to which is assigned the same signal, tends to respond, but is blocked by lugs 51 on the blocking bar 55 or its auxiliary section iii8.- Bails 69 and H do not directly initiate an operation of the linecasting machine, but instead, effect a supervisory control over the linecasting machine control unit, in that they set in operation the ratchet feed mechanism which, after a predetermined interval of operation, shifts the blocking bar 55 and its auxiliary section 108 to permit the initiation of an operation controlled by one of the selectable bars 58 and 59 or by one of the selectable bails 67 and 58. The bails 69'and 1| comprise the hereinbefore mentioned secondary selection bails.

. The several selectable elements 56 are cyclically withdrawn by a spreader cam (not shown) carried upon a shaft 99 driven through the worm gears 95 from the record reader operating shaft 25. In order to restorerconcurrently any of the bails 64 through 69 or H which might also be selected, a cam 96 is provided corresponding in its angular position to the spreader cam which serves the general class of selectable elements 56. When the apices of cam 96 encounter the follower roller .91, there is imparted a counterclockwise movement to lever 98 which is articulated at 99 to a stripper bail Ifll which opposes the action of the several bail springs 10. In this manneritheseveral selectable elements 56 and 65 through 69 and l I. are simultaneously restored under the control of a single shaft 94.

A method of correlating certain separated ones exclusively of the individually selectable members of a permutation arrangement in which alternative signal conditions are factors of a definite unit signal comprising the steps of grouping together duplicate members having signal conditions similar to those of certain of said permutation arrangement and selectable concurrently therewith, presenting in the paths of movement of said duplicate members a common motion recipient to embrace the range of the group thereof, and actuating a preparatory con- V ones of the individually selectable members of a permutation arrangement inwhich alternative signal conditions are factors of a definite unit signal which comprises the steps of grouping duplicate members having signal elements similar to all but one of the elements of two of said permutation arrangement and selectable concurrently with the selection of either of said two associated members of said arrangement, presenting a motion recipient common to said members of said group, and actuating a preparatory control function under the supervision of said recipient.

17. A method of correlating sporadic pairs of a system of selectable code elements which comprises the steps of grouping secondary selectable elements selectively conditioned concurrently With the selection of either element of each of said pairs, operating a common motion recipient by said secondary selectable elements, and initiating a supervisory control function in response to the actuation of said supervisory element.

18. In a linecasting and composing machine,

an automatic control unit for initiating line comelement being selectable in response tothe signals of one or more of the elements of said principal group, a common motion recipient actuated by the movement of any of said auxiliary ele-' ments, and a mechanism of supervisory control actuated by said common motion recipient as a result of the movement of one of said auxiliary elements for directing the performance of its corresponding principal element.

19. In a mechanism for supervising and concipal function members assembled adjacent said selectors in a predetermined arrangement to accommodate its control operations, each of said members being individually responsive to one permutable disposition of said selectors, a plurality of auxiliary members assembled together adjacent an extended portion of said selectors and each responsive by a selective movement to permutable dispositions and associated with one or more of said principal members, a supervisory apparatus for modifying the performance of said principal function members, and a common motion recipient initiated by the selective movement of any of said auxiliary members for actuating said supervisory apparatus.

20. A method of achieving any predetermined number of selective conditions naturally available in accordance with a geometric progression, which comprises the steps of grouping together a plurality of selectable elements, and coding selecting members to select each selectable element in response to a number of code combinations equal to one of the terms of said geometrical progression so that the arithmetical total of such terms shall equal said predetermined member.

21. A method of making a common motion recipient responsive to any arbitrarily determined number of permutation code combinations naturally available in accordance with a geometrical progression, which comprises the steps of modifying certain ones of a set of permutation bars with respect to certain selectable elements so that one or more of said elements shall be responsive to a plurality of code combinations equal in number to one of the terms of said progression and the total number of code combinations to which said elements shall be responsive shall equal said predetermined number as well as the sum of certain of the terms of said progression, and presenting said common motion recipient in the field of selectional movement of said certain elements.

22. Amethod of correlating a sporadic arrangement of permutation elements which comprises the steps of grouping together duplicates of certain of said elements to be correlated, interassociating a common actuator with all of said duplicates, motivating said common actuator under the control of any one of said duplicates, and performing a preparatory function affecting any of the certain of said elements under the control of said common actuator.
